我想使用total.js平台编写一个单页应用程序，从“coinmarketcap.com”api获取硬币列表，并将响应存储到数据库中。我做了以下几件事。但是我在存储接收到的信息时出错。如何将收到的json文件保存到数据库或文件系统，并在其他地方使用

1-我在“models”文件夹中编写了一个名为“coins.js”的文件，其中包含以下代码

// For importing
const Fs = require('fs');

NEWSCHEMA('UsdPrice').make(function(schema) {
schema.define('price', Number);
schema.define('volume_24h', Number);
schema.define('percent_change_1h', Number);
schema.define('percent_change_24h', Number);
schema.define('percent_change_7d', Number);
schema.define('market_cap', Number);
schema.define('last_updated', Date);
});

NEWSCHEMA('Coin').make(function(schema) {

schema.setSave(function($) {

    var model = $.model;
    var coin = U.extend({}, model.$clean());

    // Extends model
    coin.dateadded = F.datetime;

    NOSQL('coins').insert(JSON.parse(JSON.stringify(coin)));
  });
});

exports.install = function() {
ROUTE('/', viwe_index);
ROUTE('POST /api/coins/  *coin --> @save');
};

function viwe_index() {

var self = this;

RESTBuilder.make(function(builder) {

首先，

AJAX

是jComponent函数，所以前端库不是后端total.js库

请尝试此代码，我没有API密钥，因此无法尝试

控制器：


exports.install = function() {
    ROUTE('/', view_index);
};

function view_index() {

    var self = this;

    RESTBuilder.make(function(builder) {
        builder.url('https://pro-api.coinmarketcap.com/v1/cryptocurrency/listings/latest? start=1&limit=2&convert=USD');
        builder.header('X-CMC_PRO_API_KEY', 'b54bcf4d-1bca-4e8e-9a24-22ff2c3d462c');
        builder.accept('application/json');
        builder.header('Accept-Encoding', 'gzip');
        builder.exec(function(err, response) {

            // Here you could change response to your model
            var model = response;

            // Save to database without callback
            // For usage please read docs: https://docs.totaljs.com/latest/en.html#api~global~%24SAVE 
            $SAVE('Coin', model);

            self.view('index');
        });
    });
}

架构文件的一部分：

schema.setSave(function($) {
    var model = $.clean();
    // Extends model
    coin.dateadded = F.datetime;
    NOSQL('coins').insert(model);
});

请阅读response，response.data中有对象数组

控制器

exports.install = function() {
    ROUTE('/', view_index);
    // or
    // ROUTE('/');
};

function view_index() {

    var self = this;

    RESTBuilder.make(function(builder) {
        builder.url('https://pro-api.coinmarketcap.com/v1/cryptocurrency/listings/latest?start=1&limit=2&convert=USD');
        builder.header('X-CMC_PRO_API_KEY', '07c1f1d1-681a-467e-8558-923da4d815c2');
        builder.accept('application/json');
        builder.header('Accept-Encoding', 'gzip');
        builder.exec(function(err, response) {

            var data = response.data;

            data.wait(function(item, next) {

                // Schema save
                $SAVE('Coin', item);

                // Or save directly to NOSQL
                // NOSQL('coins').insert(item);
                next();
            }, function() {
                self.view('index');
            });

        });
    });
}

模式

    schema.setSave(function($) {
        var model = $.clean();
        // Extends model
        model.dateadded = F.datetime;
        NOSQL('coins').insert(model);
    });

您的建议有效，但以空值保存。（null，“，zero）。我的数据库记录：

{“id”：0，“name”：“symbol”：“slug”：“num_-market_-pairs”：0，“date_-added”：null，“tags”：[]，“max_-supply”：0，“circulation_-supply”：0，“platform”：“cmc_-rank”：0，“last_-updated”：“null”，“quote”：[]，“USD”：[]}

您能用这个api密钥测试吗？”07c1f1d1-681a-467e-8558-923da4d815c2“
